% TITLEREF.STY ver 3.1 2001-04-05 Donald Arseneau <asnd@triumf.ca>
% This is free unsupported software, released to the public domain.
%
% This package provides a "\titleref" command to cross-reference the titles
% of sections. The "\label" command is changed to remember the title for
% such a reference. Use "\titleref" just like "\ref" and "\pageref".
%
% Titles for numbered sectioning units and for floats with captions are
% the same as the respective TOC, LOF, or LOT entry (even when no TOC is
% printed). When a short title is provided ("\section[short]{long}")
% it will be used for the "\titleref". This is especially useful for
% figure captions. Unnumbered sections take their title reference from
% the printed title. Beware! This turns the title into a moving argument
% when it normally is not, and will cause weird errors if there are
% `fragile' commands present.
%
% Enumerated lists do not have titles and simply inherit the title of
% their section.
%
% The format of the title reference is controlled by the command
% "\theTitleReference", which can be redefined with "\renewcommand".
% It takes two parameters: the number and the title. The number is
% just the regular "\ref" and it is WRONG in unnumbered sections.
% Beware! The default definition is the unadorned title. You could
% do, for example, "\renewcommand{\theTitleReference}[2]{#1\ \emph{#2}}".
%
% The title of the current section is also available without "\label":
% Use the command "\currenttitle" to generate a "\titleref" to the current
% section. If you have redefined "\theTitleReference" to print the number
% with the title, be aware that the two may not correspond: In a numbered
% list the number will show the current item but the title will show the
% current section, but in an unnumbered section the number will show
% some previous section number.
%
% Options: [usetoc] and [nostar]
%
% In the default operation, the titles are recorded by a command inserted
% into the various sectioning commands ("\@sect", "\@ssect", "\@chapter",
% "\@schapter", "\@part", "\@spart", and "\@caption"). If this creates
% conflicts with some other package, you can use an entirely different
% method by specifying "\usepackage[usetoc]{titleref}". As the name
% implies, this option records the titles from the table-of-contents
% entry without redefining the sectioning commands. (This is the method
% used in older versions.)
%
% Since there are no TOC entries for the `star' versions of sectioning
% commands, they are still redefined. The additional option "[nostar]"
% ("\usepackage[usetoc,nostar]{titlerrf}") prevents the redefinitions,
% but then "\section*" will not generate a title reference. If you try
% to refer to the title of an unnumbered section while "[nostar]" is in
% effect, you will get the title of the previous section.
%
% Under the "[usetoc]" option, the current title will always be overridden
% by an "\addcontentsline" command before the "\label", even for starred
% section commands under the "[nostar]" option.
%
% The big problem with the "[usetoc]" method is that "\titleref" will
% not refer to a "\label" which was given in the title or caption itself;
% the label must be placed after the sectioning command or the caption.
% If you make a title-reference to a label given in a title, you will get
% a warning message.
